Description
From the beginning of refueling, the air and vapor inside the fuel tank go via the refueling EVAP vapor cut valve and EVAP/ORVR line to the EVAP canister. The vapor is absorbed by the EVAP canister and the air is released to the atmosphere.
When the refueling has reached the full level of the fuel tank, the refueling EVAP vapor cut valve is closed and refueling is stopped because of auto shut-off. The vapor which was absorbed by the EVAP canister is purged during driving.
WARNING: When conducting inspections below, be sure to observe the following:
CAUTION:
Continued refueling may cause fuel overflow, resulting in fuel spray and possibly a fire.
Component Function Check
1.CHECK ORVR FUNCTION
Check whether the following symptoms are present.
Diagnosis Procedure
1.INSPECTION START
Check whether the following symptoms are present.
2.CHECK EVAP CANISTER
The weight should be less than 2.1 kg (4.6 lb).
3.CHECK IF EVAP CANISTER IS SATURATED WITH WATER
Check if water will drain from EVAP canister
4.REPLACE EVAP CANISTER
Replace EVAP canister with a new one.
5.CHECK DRAIN FILTER
6.DETECT MALFUNCTIONING PART
Check the EVAP hose between EVAP canister and drain filter for clogging or poor connection.
7.CHECK REFUELING EVAP VAPOR CUT VALVE
8.CHECK EVAP CANISTER
The weight should be less than 2.1 kg (4.6 lb).
9.CHECK IF EVAP CANISTER IS SATURATED WITH WATER
Check if water will drain from EVAP canister.
10.REPLACE EVAP CANISTER
Replace EVAP canister with a new one.
11.DETECT MALFUNCTIONING PART
Check the EVAP hose between EVAP canister and drain filter for clogging or poor connection.
12.CHECK VENT HOSES AND VENT TUBES
Check hoses and tubes between EVAP canister and refueling control valve for clogging, kinks, looseness and improper connection.
13.CHECK FILLER NECK TUBE
Check recirculation line for clogging, dents and cracks.
14.CHECK REFUELING EVAP VAPOR CUT VALVE
15.CHECK FUEL FILLER TUBE
Check filler neck tube and hose connected to the fuel tank for clogging, dents and cracks.
16.CHECK ONE-WAY FUEL VALVE-I
Check one-way valve for clogging.
17.CHECK ONE-WAY FUEL VALVE-II
When a stick is inserted, the valve should open, when removing stick it should close.
Do not drop any material into the tank.
Component Inspection
REFUELING EVAP VAPOR CUT VALVE
1.INSPECTION START
2.CHECK REFUELING EVAP VAPOR CUT VALVE
With CONSULT
Blow air into the refueling EVAP vapor cut valve (from the end of EVAP/ORVR line hose), and check that the air flows freely into the tank.
Always replace O-ring with new one.
3.CHECK REFUELING EVAP VAPOR CUT VALVE
Without CONSULT
Blow air into the refueling EVAP vapor cut valve (from the end of EVAP/ORVR line hose), and check that the air flows freely into the tank.
Always replace O-ring with new one.
